Swagger/OpenAPI Explorer

This Swagger/OpenAPI MCP server enables AI assistants to dynamically load and explore API specifications from URLs or files, providing comprehensive endpoint discovery and documentation access. Built with TypeScript using the @apidevtools/swagger-parser library, it offers four core tools for loading API specs, retrieving detailed endpoint information with optional natural language summaries, listing all loaded APIs, and searching endpoints by pattern matching. The implementation supports multiple concurrent API specifications through unique identifiers and provides both structured JSON responses and human-readable summaries, making it valuable for API integration workflows where assistants need to understand and interact with external services by first examining their OpenAPI documentation.
